Description

Hi,

Not sure if you want to fix this or not. I noticed the following error and logs fail to rollover and causes a problem. It could cause a problem i guess if someone makes some kind of mistake of file suffix during support. Maybe you want to just skip those invalid files? It seems like it was a recent log4j2 change (maybe 2.8.x) since these files have been there since 2016 and previous log4j2 versions didn't complain. Looks like maybe support renamed some previous log files to have unix system time in the suffix like file.log.1457052422478.
